Classify the reactions as endothermic or exothermic. a. the reaction between ammonium nitrate and water absorbs heat from the surrounding environment. b. three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes the beaker hot. c. ammonium chloride dissolved in a beaker of water makes the beaker cold. d. uranium atoms are split to produce nuclear energy. e. water separates into hydrogen and oxygen when an electric current is run through it. f. methane and oxygen are combined to produce methanol and heat.

A - Endothermic. This is because it absorbs heat rather than releases it.

B - Exothermic. It's releasing heat which in turn makes the beaker hot.

C - Endothermic. The Ammonium Chloride is absorbing the heat away from the beaker.

D - Exothermic. To produce nuclear energy, it needs to release heat.

E - Endothermic. The hydrogen and oxygen atoms are absorbing the heat given off from the electric current.

F - Exothermic. It is producing heat or releasing heat.

Exothermic is the losing, release, or production of heat. Endothermic is the exact opposite; it is the storing of heat.

Hope this helps!
